APPLIANCE Fon USE wI'rH York, have made a new and useful Invention in `Appliances for Use with Telephone- Tiansmitters, of which the following is a speciiication.

Our invention is directed to improvements in appliances for enabling the users of telephones to hold'coiiversatioii with other siibscribers in such manner that persons in thev same room whereA the transmitter is located will not hear any part o' the conversation, and particularly to an improvement upon 'an apparatus of this nature disclosed in an application for a patent liled in the U. S. tatcnt Oilice byv Orrin H. Goodrich, on the 4th dayV of January, 1908, Serial No, 409,327.

Oui' inventionwill be fully understood by referring to the accompanying drawings, in

which,

Figure 1 is a vertical. sectional view thereof taken througlithe center of Fig. 2, the telephone transmitter aiid its switching attach ments and the flexible conductors being shown in side elevational view, the means of y fastening 'the door of the box being shown in dotted lines. Fig. 2 is a front elevational 'View as seen looking at Fig. 1 from left to right uponthe supposition that the inclosing door of the box or casing has been removed, the upper leftliand portion of said inclosing box beingshown in broken section; the transinitter, the receiverfthe ilexible conductors for the' receiver, and the operative switching connections being shown in elevational view.

The Abefore-mentioned applicationdiscloses a box or casing for inclosin'g the transmitter of a portable or desk telephone,-said box being lined interiorly with a sound absorbing medium, such as felt, and provided also with means for securing'the transmittery directly to the bottom and the back of the box interiorly, the arrangement being such that the transmitter is removed bodily with Specification of Letters Patent.

the bottom by the withdrawal of screws; me clianically actuated switching connections being also connected With the box in such manner that the receiver of the outfit may be suspended upon a fork exterior to the box and perform' the functions of cutting inthe transmitter and cutting out the call circuit, or vice versa, in the usual Way. The 'transe4 mittei is supported in such manner that the mouth piece thereof is located substantially-l side near the upper end of the box, said open# ing having the contour ci the lower portion `of a persons face and )iiwided with an expansible tube, preferably o' rubbei` filled with air, the arrangement being such that When the face of the person is inserted in the facial opening and the receiver removed from the exterior hook conversation may be held With another outlying subscriber and suoli conversation not heard by persons iii the same room wlii-iri'iy the transmission is be- ,ing effected. r'he inif'entioi'i thus disclosed is of such a. nature that the transmitter and its interconnected switching mechanism can only be removed by unscrewing the bottoni ci' the box, disconnecting the conductors running to the transmission circuit, the receiver and the call circ'uit, thereby occasioiiing much inconvenience to such persons as :ire called upon to examine and repair apparatus oi this nature.

The present invention has for its objects-First, the sin'ipliiication ci thcappaiatus disclosed in the before-mentioned iipplication to such an extent aste permit ot the entire transmitter of a portable or desk tele )hone and its interconnected switching removed 'or taken away from. the casing without necessitating the removal of practically permanent parts, 'such' as screws, holding devices, binding posts,`etc. Second,

any authorized person may use the inclosin'g box or casing in alinem'eiit with a' facial opening at onev mec', anisni and the-receiver and the yinter-5y p connecting flexible conductors being bodilyl to provide means whereby the subscriberorl without being subjected to tlie' annoyance of having his hat displaced or removed from his head, as was the case with- .the lining of the box.

Referring now to the drawings in detail, 1 represents the standard, 2 the transmitter, 8 the receiver, 4 the circuit changing lever, and 5, 6 the circuit changing forks of a wel] known form of ortable or desk telephone, 37 and 38 being t e double or duplex flexible conductors insulated from each other and provided with the usual braided covering.

7 represents the inclosing box or casing preferably of wood and of suitable dimensions to wholly inclose the transmitter and its associated parts, as shown.

9 and 11 represent relatively thick sheets 0f sound absorbing medium, such as felt, separated from each other by a lining l() of thin sheet rubber, leather, or the like, three of the inner walls and the top and bottom thereof being thus lined, and not substantially different from the like parts disclosed in the before-mentioned application.

8 represents a thin lining secured to the inner surface of the lining 1] and made preferably of some water resisting material, such as Celluloid, hard rubber, mica, or the like, said lining being for the purpose, as before stated, of giving to the interior ofthe box the best antiseptic conditions-and for enabling the same to be cleansed or Washed at will.

15 represents a door hinged to the box properl at its lower end by hinges 31, and adapted to close the entire front of the box, saidlv door being provided as shown with similar linings 8, 9, 10 and 11, to those of the Y interior walls of the box.

12 is an elliptical extension secured to the outer surface of the door and having at its outer end a facial opening, corresponding to the contour of the lower portion of persons face, in the inner surface of which is secured by a flange 18 and metal ring 13 a flexible facial tube 34 identically like that disclosed in, the before-mentioned application, the function of this elliptical extension 12 being to remove the facial opening to such a distance from the body of the box proper and the top thereof that when a person is talking there Will be no danger of having his-hat disturbed by coming into contact with the front face of the inclosing box or casing. Such an extension also makes it possible to more ell'ectually adjust the pivoted transmitter 2 with relation to the mouth of the speaker by increasing the distance between the transmitter and the point of facial support. It will be noted that this facial extension 12 is lined interiorly as were the inner Walls of the box 7 and the door 15. These features constitute important elements of our improvement.

the box held above the bottom proper so as to constitute an air chamber, a similar air chamber being shown at the top thereof, said chamberbeing adapted to further aid in the insulation of the sound Waves.

16 is a metal ring having substantially the contour of the base of the portable or desk telephone set and adapted to detachably secure the same in the manner shown.

17, 17 aie notches located in the front 14 represents a supplemental bottom of l edges of the sides of the box, their function being to permit of the insertion of the conductors 37, 38 in such manner as to hold them in position when the door is closed, as ashown in Fig. 1.

19 is an oblong slot in one side of the box and 20 is a metallic face plate similarly slotted and secured thereto.

21 is a circuit changing arm provided with forks 33, 33 similar to the forks 5 and 6, and 22 is a cylindrical extension adapted to move vertically in the slot 19 inthe side of the box, said cylindrical 'extension being connected directly to a vertical sliding yoke 23, the upper end of which is sustained directly by a leaf spring 24 at the top of the casing. T o the lower end of the inner part of the yoke 23 is secured an extension 26 by a set-screw 27 extending through a slot 28 for adjusting its vertical height, these parts constituting the interconnecting switching means being sub.- stantially like similar parts disclosed in the before-mentioned application. The lower end of the extension 26 is provided with a cross-arm 29 curved on its under surface to correspond with the curvature of the two ends of the fork 6, 6, 3G being a central extension passing downward between said. forks, the arrangement being such that when the telephone receiver 3 is held in position o n the exterior forks '33, theV weight thereof is sufficient to cut out the-transmitter circuit and include the bell circuit in the usual Way.

25, 25 are hooks pivotally secured near the front edges of the box 7 and adapted to secure the door in closely locked position through Ithe agency of two pins 32, `32 on the lateral edges thereof, 'the entire arrangement being such that when the door is thus closed the mouth of the transmitter 2 is iny alinel ment with that portion of the facial opening Which makes it possible for a user to talk directly into said transmitter with his face firmly held against the flexible tube 34 so that by noy possibility can there be any ex- -under the'ends of the cross-arm 29, and removed wholly from the interior of the box in the direction of the tailed arrow; a like action With the other hand removing the receiver 3 so that the box or casing and its attachments and the telephone 'are thus absolutely separated from each other with a minimum eilort and without any inconvenience whatever to the inspector. `With such an arrangement, therefore, We are enabled to place at the `hands of a subscriber a secret telephone box or'casing which adapts itself for use in oliices or in public places where secret transmission is important and this without in any way interfering with the functions of the employees of Athe lessors. It is also apparent that Such 'an inclosing box or casing makes it possible for the user to take the transmitter out lof the casing, hang the receiver 3 upon the fork 6 and replace the two wholly'inside the 'box or casing, after which the door 15 may i be locked in any preferred way so as to prevent unauthorized personsvv from using the instrument, thus constituting a valuable feature for preventing unauthorized calls and at kthesame time 'wholly protecting the complete outfit from damage, such as often occurs with portable or desk telephones where emplolyi/Ieles in cleaning oilices sometimes caiey ock them over and seriously damage the arts.

V e-do not limit our invention to the especial details of construction hereinbefore describedand illustrated in the accompanying drawings, as a number of the features might 'be departed from te a certain extent and still come Within the sco 'e of our claims hereinafter made.` We be ieve it is broadly new Withlus to devise a secret telephone box or casing' for aportable -or desk telephone set which permits of the' instantaneous removal or detachment of the complete outfit from interconnection with the box without necessitating the removal of screws or relatively permanent fixtures, and our claims are to be lconstrued as of the most generic nature in this respect.

Having thus described our invention what we claim and desire to secure by Letters Patent of the United States .is-
